Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

Etymology
From any intrusive igneous rock, having a majority of carbonate minerals
From Auvergne region of France used by a French geologist Alexandre Brongniart in 1826 who applied this term to some feldspathic sandstones

Formation
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Carbonatite vs Arkose Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Carbonatite vs Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Arkose. Learn more about Carbonatite vs Arkose in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Carbonatite and Arkose, they have various applications in construction industry. The uses of Carbonatite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Unknown, Unknown and that of Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Carbonatite and Arkose
Here you can know more about Carbonatite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Arkose consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas, Arkose is available in reddish brown colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Arkose is Rough and Dull. Properties of rock is another aspect for Carbonatite vs Arkose. The hardness of Carbonatite is 3 and that of Arkose is 6-7. The types of Carbonatite are Not Available whereas types of Arkose are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Arkose is white. The specific heat capacity of Carbonatite is Not Available and that of Arkose is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Carbonatite is heat resistant, pressure resistant, water resistant whereas Arkose is heat resistant, impact resistant, pressure resistant.
